FIELD OF THE INVENTION
[0001] This invention relates generally to transmission lines, and in particular to transmission
line hangers for supporting transmission lines used in antenna systems.
BACKGROUND OF THE INVENTION
[0002] Transmission line hangers are used to support transmission lines. Transmission lines
are supported by attaching them to supporting structures by transmission line hangers.
The most extensive use of hangers is in connection with coaxial cables, such as those
disclosed in U.S. Patent No. 5,334,051 (Devine et al.) and 5,167,533 (Rauwolf). Coaxial
cables are extensively used for carrying a variety of electromagnetic signals. In
most uses, the cables need to be attached to a supporting structure along most of
their lengths.
[0003] Transmission line hangers are also used for supporting waveguides which carry electromagnetic
signals from transmitting or receiving equipment in an equipment shelter to an antenna
mounted on a tall tower. A large number of hangers are required to support a waveguide
beneath a horizontal waveguide bridge extending between the shelter and the base of
the tower and to support the waveguide on the tower as the wave guide extends upwardly
to the antenna. An even larger number of hangers are required where separate waveguides
extend to several antennas on a signal tower. Commercially available waveguides have
a variety of cross-sectional shapes. For example, a variety of waveguide shapes are
disclosed in U.S. Patent Nos. 3,822,411 (Merle) and 4,047,133 (Merle).
[0004] A typical hanger for elliptical-shaped waveguides includes a generally U-shaped clip
adapted to be attached to a support member on the bridge or the tower by a bolt extending
through a hole in the support member and held in place by a nut and lock washer. After
the hangers have been attached to the support members, the waveguide is strung along
the bridge, up the tower and clamped between the legs of each U-shaped hanger by tightening
a clamping screw which extends between the legs. A considerable amount of installation
time is required, first to attach the large number of hangers to the bridge and the
tower and then to clamp the waveguide within the hangers. In addition, a large amount
of auxiliary hardware (
e.g., screws, bolts, nuts and washers) is required along with the hangers themselves.
[0005] A spring hanger system for supporting a VHF circular waveguide is disclosed in U.S.
Patent No. 4,654,612 (Smith). A variety of prior hangers for microwave transmission
lines are disclosed in Andrew Corporation Catalog #36. An improved waveguide hanger
is disclosed in U.S. Patent No. 4,763,132 (Juds et al.). The waveguide hanger disclosed
in the Juds et al. patent is in the form of a resiliently yieldable and generally
U-shaped clip 1, illustrated in FIG. 1, that is adapted to be slipped over an elliptical
waveguide and snapped into a supporting member. The clip includes a hinge portion
2 that extends between the legs 3 of the clip 1.
[0006] Another cable hanger is disclosed in U.S. Patent No. 5,393,021 (Nelson). As illustrated
in FIG. 2, the cable hanger 200 disclosed there includes a hinge section 320, a cable
retention section 340, and a structure attachment section 360 having two locking members
580 that each include a pair of concave locking barbs 600. Cable hangers that include
hinges can only accommodate a limited range of cable diameters. The maximum cable
diameter accepted by such cable hangers is limited by the maximum circumference of
the cable retention section.
[0007] Prior cable hangers, such as Nelson and Juds et al., also place the cable retention
section close to the attachment section. Thus, the attachment section is traditionally
short in length. This makes the attachment section rigid and non-compliant which makes
installation of such hangers difficult especially where a large diameter cable is
being installed on a tower or where the weather conditions limit manual dexterity,
e.g., cold weather. In such situations, tools may be required to squeeze the hanger into
the tower aperture. The use of tools is undesirable especially where a cable is being
installed on a high tower.
[0008] Furthermore, some prior hanger designs do not adequately prevent longitudinal movement
of the cable with respect to the hangers. Hangers without mechanisms for penetrating
or biting into the cable jacket can not prevent longitudinal movement of the cable
because the frictional coefficient between the metal hanger and the plastic cable
jacket is very low, since the polyethylene typically used for cable jackets is a soft
material that has an inherent lubricant quality. In addition, the cable jacket can
"cold flow" which reduces the holding force of the cable hanger over time, resulting
in cable slippage.
The installation of transmission line hangers is often a difficult and time-consuming
operation because of the large amount of auxiliary hardware required to install some
prior hangers. Therefore, there is a continuing need for efficient, inexpensive hangers
and for improved methods of installing them. The present invention addresses these
needs by providing a transmission line hanger that can be easily and efficiently installed,
is expandable to accommodate a large number of transmission line diameters, and can
reduce longitudinal movement of the transmission line within the hanger, and is inexpensive
to produce.
SUMMARY OF THE INVENTION
[0009] In one aspect, a transmission line hanger is provided for securing a transmission
line to a supporting structure having an aperture defined by a wall. The transmission
line hanger includes a partially cylindrical member for accommodating a transmission
line. The partially cylindrical member includes a first leg and a second leg each
respectively extending from the partially cylindrical member. The first and second
legs allow the hanger to accommodate various sizes of transmission lines. The first
and second legs each include a first section for contacting the wall of the aperture
at one of a pair of contact points, and a second section extending from the first
section and forming a locking barb configured to lock against the supporting structure
once the locking barb is inserted through the aperture.
[0010] In another aspect, a transmission line hanger is provided for securing a transmission
line having a protective jacket to a supporting structure having an aperture defined
by a wall. The transmission line hanger includes a transmission line retention section
for retaining a transmission line. The transmission line hanger further includes an
extended section extending from the retention section. The extended section includes
a spring finger flexibly connected thereto, and projecting inwardly therefrom. The
spring finger is configured to penetrate into the jacket once the transmission line
is inserted into the hanger. The spring finger minimizes longitudinal movement of
the transmission line with respect to the hanger. The extended section, in conjunction
with the spring finger, allows the hanger to accommodate a large range of different
transmission line diameters.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
[0012] It has been discovered that transmission lines can be efficiently and inexpensively
supported by using unitary transmission line hangers, such as a transmission line
hanger 10 according to the present invention. A unitary hanger is cheaper to produce
and more reliable than hangers composed of several pieces. However, a hanger having
two or more pieces that are, for example, welded together, would function the same
as the unitary hanger described herein.
A plurality of transmission line hangers 10 are used to support a variety of types
of transmission lines, including circular coaxial cables and waveguides, having a
variety of diameters. A plurality of transmission line hangers 10 generally secure
one transmission line to a supporting structure, such as a horizontal transmission
line bridge or a vertical antenna tower. The transmission line hangers 10 are easy
to install because no ancillary hardware is required such as nuts, bolts or screws.
[0013] The present invention will now be described in connection with the embodiments shown
in the drawings. Referring first to FIGS. 3a and 3b, the transmission line hanger
10 and a supporting structure 5 are illustrated. In the illustrated embodiment, the
hanger 10 is a unitary structure essentially composed of metal. In one embodiment,
the hanger 10 is composed of stainless steel having a thickness of 0.76 mm. The illustrated
hanger 10 includes a transmission line retention section 100, an extended section
105 and an attachment section 110. The transmission line retention section 100 includes
a partially cylindrical member 12 that accommodates a transmission line. The partially
cylindrical member 12 includes a first leg 14 and a second leg 16 that comprise the
extended section 105. The first leg 14 and the second leg 16 each respectively extend
from the partially cylindrical member 12. A compliant area 13 is disposed between
the legs 14 and 16, respectively, and the partially cylindrical member 12 and allows
the first and second legs 14 and 16 to be pressed together. In one embodiment, the
extended section 105 includes a pair of spring fingers 29 projecting inwardly from
the extended section 105 and into the transmission line retention section 100, as
illustrated in FIG. 3a.
[0014] The compliant area 13 between the legs 14 and 16 and the partially cylindrical member
12, in conjunction with the spring fingers 29, allow the hanger 10 to have the necessary
compliance to accommodate a large range of different transmission line diameters.
The extended section 105 has the compliance to allow the hanger 10 to accommodate
a large range of transmission line diameters and still allow the attachment section
110 to be inserted into the supporting structure 5. Prior hangers without an extended
section between the transmission line retention section and the attachment section
had essentially no compliance. Thus, in these prior designs, if a transmission line
larger than the diameter that the transmission line retention section could accommodate
was inserted into the hanger, then the attachment section would not be able to be
squeezed to allow the attachment section to be inserted into an aperture in the supporting
structure.
[0015] Unlike prior hangers, the shape of the retention section 100 and the attachment section
110 of the hanger 10 do not change significantly in response to supporting different
diameter transmission lines. In contrast, the pliability of the spring fingers 29
allows the spring fingers 29 to flex inward with respect to the extended section 105.
The pliability of the extended section 105 allows the attachment section 110 to be
inserted into the supporting structure 5 without significantly changing the shape
of the transmission line retention section 100 despite different diameter transmission
lines being supported by the hanger 10.
Referring again to FIGS. 3a and 3b, the attachment section 110 includes a first section
18 that extends from each of the first and second legs 14 and 16, respectively. The
supporting structure 5 includes a circular aperture 50 defined by a wall 52. The first
section 18 contacts the wall 52 at one or both of the pair of contact points 54 and
56. A second section 20 extends from the first section 18 and forms a locking barb
22 that is configured to lock against the supporting structure 5 once the locking
barb is inserted through the aperture 50. The supporting structure 5 includes an outer
surface 58 and an inner surface 60. The surfaces of the supporting structure may be
rough due to, for example, irregularities, bubbles and/or barbs caused by the galvanizing
process and/or the punching process that produces the aperture 50. Therefore, each
locking barb 22 includes a barb contact point 23. Each locking barb 22 contacts the
inner surface 60 of the supporting structure 5 at the barb contact point 23. Because
the hanger 10 includes two locking barbs 22, one on each leg (14, 16), the hanger
10 can be more securely attached to the supporting structure 5 despite any irregularities
on the inner surface 60. As best illustrated in FIG. 3b, the locking barb 22 is integral
with the second section 20 and extends from and is generally orthogonal thereto.
[0016] The wall 52 of the aperture 50 may also be rough because of irregularities, bubbles
and/or barbs caused by the galvanizing process and/or the punching process that produces
the aperture 50. Therefore, in one embodiment, contact with these irregularities is
minimized by having the first section 18 of the hanger 10 only contact the wall 52
at one or both of the pair of contact points 54 and 56.
[0017] As best shown in FIGS. 3a and 4, in one embodiment, the compliant area 13 is provided
by a fulcrum or bend. The compliant area 13 enables the first and second legs 14 and
16 to be pressed together thus allowing the locking barbs 22 to fit through the aperture
50 in the supporting structure 5. The compliant area 13 also allows the first and
second legs 14 and 16 to expand by spring force once the locking barb 22 is inserted
through the aperture 50. This expansion brings the first section 18 into contact with
the wall 52 of the aperture 50 at one or both of the pair of contact points 54 and
56.
[0018] The design of the hanger 10, and in particular the extended section 105, allows for
easy installation of the hanger 10. Specifically, the extended section 105 allows
larger diameter transmission lines to be inserted into the hanger 10. The user then
wraps his or her fingers around the hanger 10, and the transmission line therein,
and presses the legs 14 and 16 together. The extended section 105 places the transmission
line retention section 100 further away from the supporting structure 5. In addition,
the attachment section 110 is closer to the user's fingers and thumb thus allowing
a greater range of motion and greater force to be applied to the hanger 10 when inserting
the attachment section 110 into the supporting structure 5. The extended section 105
also gives the user more room to work, and avoids the user's hands from hitting the
supporting structure 5 during installation.
[0019] The design of the hanger 10, and in particular the extended section 105, also provides
a more dynamic snap-in action than prior hangers when the hanger 10 is installed into
a supporting structure. The two locking barbs 22 also provide less insertion resistance
than prior hanger designs having four locking barbs. Having only two locking barbs
22 reduces the number of contact points that must contact the outer surface 58 of
the supporting structure 5 during insertion of the hanger 10 into the supporting structure
5. Additionally, the two barb design of the attachment section 110 reduces insertion
resistance by reducing the cam pressure required and the amount of deflection required
to insert the hanger 10 into the supporting structure 5. This reduces the amount of
force required to insert the hanger 10 into a supporting structure. The hanger 10
thus requires less manual dexterity to install and uninstall than prior hangers. In
addition, the ergonomical design allows for easier installation. These are important
features especially where the typical transmission line is in excess of 1,000 feet
and a hanger is mounted every three feet. Consequently, hundreds of hangers must be
installed to support such a transmission line. The man hours required for such an
installation is great. Accordingly, transmission line installation is costly. In addition,
it can be difficult to find someone willing to install such hangers high above the
ground, especially if extra hardware is required to install the hangers. Therefore,
a hanger that requires less installation time and that is easier to install reduces
the man hours required for installation, thus reducing installation costs.
[0020] The pair of spring fingers 29 are best illustrated in FIG. 6. The first leg 14 includes
one of the pair of spring fingers 29 flexibly connected thereto, and projecting inwardly
therefrom. The second leg 16 includes a second of the pair of spring fingers 29 flexibly
connected thereto, and projecting inwardly therefrom. The spring fingers 29 are flexibly
connected to the legs 14 and 16 such that when a transmission line is inserted into
the hanger 10 the spring fingers 29 flex outward with respect to the legs 14 and 16,
respectively, and force the transmission line against the top potion 30 of the partially
cylindrical member 12. Thus, the spring fingers 29 provide spring resistance against
the transmission line after it is inserted in the hanger 10. The spring fingers 29
also penetrate or bite into the jacket of the transmission line to further secure
the transmission line within the hanger 10. The spring fingers 29 help minimize the
longitudinal movement of the transmission line in the hanger 10. Longitudinal movement
is defined as movement in a direction parallel to the length of the transmission line.
The spring fingers 29 also help minimize transmission line vibration.
[0021] In another embodiment, the extended section 105 includes one spring finger 29 projecting
inwardly from the extended section 105 and into the transmission line retention section
100. For example, the first leg 14 may include one spring finger 29 flexibly connected
thereto, and projecting inwardly therefrom. The one spring finger 29 is flexibly connected
to the first leg 14 such that when a transmission line is inserted into the hanger
10 the spring finger 29 flexes outward with respect to the first leg 14 and forces
the transmission line against the top left potion of the partially cylindrical member
12. Thus, the one spring finger 29 can provide spring resistance against the transmission
line after it is inserted in the hanger 10. The one spring finger 29 also bites into
the jacket of the transmission line to further secure the transmission line within
the hanger 10. The one spring finger 29 helps minimize the longitudinal movement of
the transmission line in the hanger 10. The one spring finger 29 also helps minimize
transmission line vibration. Alternatively, the second leg 16 may include one spring
finger 29 flexibly connected thereto, and projecting inwardly therefrom, that forces
the transmission line against the top right potion of the partially cylindrical member
12. In either case, the extended section 105, in conjunction with the one spring finger
29, allows the hanger 10 to accommodate a large range of different transmission line
diameters by having the compliance to expand for larger transmission lines. The extended
section 105 and the one spring finger 29 also have the compliance to allow the hanger
10 to accommodate a large range of transmission line diameters while still allowing
the attachment section 110 to be inserted into the supporting structure 5.
[0022] In the illustrated embodiments, the extended section 105, in conjunction with the
pair of spring fingers 29, allows the hanger 10 to accommodate a large range of different
transmission line diameters by having the compliance to expand for larger transmission
lines. The extended section 105 and the spring fingers 29 also have the compliance
to allow the hanger 10 to accommodate a large range of transmission line diameters
while still allowing the attachment section 110 to be inserted into the supporting
structure 5.
[0023] No matter how the transmission line is disposed in the hanger 10, the two opposing
spring fingers 29 will provide spring resistance against the transmission line, which
in turn will force the transmission line against the top potion 30 of the partially
cylindrical member 12, and bite into the jacket of the transmission line.
In use, the hanger 10 may be installed easily and quickly on the transmission line
by pulling apart the legs 14 and 16 and slipping the hanger 10 over the transmission
line such that the partially cylindrical member 12 is disposed around the transmission
line and the spring fingers 29 are forced against the transmission line thus pressing
the transmission line against the top potion 30 of the partially cylindrical member
12. The legs 14 and 16 are then pressed together to allow the locking barbs 22 to
be inserted through the aperture 50, as illustrated in FIG. 7. The hanger 10 is inserted
into the aperture 50 until the first sections 18 snap into contact with the supporting
structure 5 at one or both of the pair of contact points 54 and 56 and the barb contact
points 23 contact the inner surface 60 of the supporting structure 5, as illustrated
in FIGS. 3a and 3b. This process is repeated for each hanger 10 that is installed
along the length of the transmission line. FIGS. 5-9 illustrate different views of
the hanger 10 installed in the supporting structure 5.
The hanger 10 can also be readily uninstalled and reused in another location. To uninstall
the hanger 10, the legs 14 and 16 are pressed together to allow the locking barbs
22 to be removed from the aperture 50. Next, the partially cylindrical member 12 is
slipped off the transmission line by pulling apart the legs 14 and 16 and disengaging
the spring fingers 29 from the transmission line jacket.
[0024] In another embodiment, the transmission line retention section 100 includes areas
of resistance 25 for retaining the transmission line and accommodating a large range
of transmission line diameters. FIGS. 10a, 10b, 11a, and 11b illustrate two embodiments
of the areas of resistance 25. FIGS. 10a and 10b illustrate two opposing areas of
resistance 25' that each include an inwardly curved portion 26' and an indentation
28'. The curved portion 26' is attached to the partially cylindrical member 12 at
each end and provides spring resistance against the transmission line after it is
inserted in the hanger 10. The indentations 28' help further secure the transmission
line within the hanger 10 by penetrating or biting into the jacket of the transmission
line. Thus, the indentations 28' minimize the longitudinal movement of the transmission
line in the hanger 10 and also help minimize transmission line vibration.
[0025] FIGS. 11a and 11b illustrate two opposing areas of resistance 25'' that each include
an inwardly curved portion 26'' and a pair of tabs 28''. The curved portion 26'' is
attached to the partially cylindrical member 12 at each end and provides spring resistance
against the transmission line after it is inserted in the hanger 10. The inwardly
bent tabs 28'' help further secure the transmission line within the hanger 10 by penetrating
or biting into the jacket of the transmission line. Thus, the tabs 28'' minimizes
the longitudinal movement of the transmission line in the hanger 10 and also help
minimize transmission line vibration.
[0026] Having two opposing areas of resistance makes the orientation of the transmission
line inserted into the hanger 10 irrelevant. No matter how the transmission line is
disposed in the hanger 10 (
e.g., the areas of resistance are in-between the corrugations of a corrugated cable or
are in contact with one of the protruding corrugations), the two opposing areas of
resistance 25 will provide spring resistance against the transmission line and the
indentation 28' or tabs 28'' will penetrate into the jacket of the transmission line.
